Try switching to a medium with more free space, or use the PC to delete files on the medium and make more free space. Can I view a list of alarm occurrences? During memory sampling, there is an alarm summary. You can display a history of up to alarms. When does FTP transmission occur? Are past data also transferred?
Files are transferred when they are created at the auto save interval or other intervals. Files created in the past are not sent, but if some files fail to transfer due to network-related or other problems, those files are sent along with the latest With display data, how do I set it up so that on an autosave of once per day it saves data from —? Set the autosave interval to 1 Day, the memory timeup to Day, and the hour to 0.
Display data. Probably your trigger settings are not correct. For details, see the following. Display and event data files I'm recording display data at a scan interval of msec. If I open the files in the viewer the data interval is 0. The fastest save interval for display data is 0. If you want to save the data at msec intervals, you'll need to use event data.
Display and event d With display data recording, if I set autosave in units of 1 day, from what data to what data constitutes "1 day"? Note that if you're also using the memory timeup function, you can start a new file at, for example, 00 hours and record 1 day's worth thereafter. On the operator page, you can switch screens from a web browser. You cannot switch screens on the monitor page.
However, you cannot access the files in internal memory. Yes, by using the Web server display function. What is the screen update interval when monitoring screens on the web? The update interval of the web monitor page is approximately 30 seconds.
What are the data types that can be sent via FTP? Why are there 1—4 alarms per channel? Four alarms levels can be set per channel. You can also set the same type of alarm for different levels. Why are there 2 data values max and min for acquired data? Because the data type is set to display data. Display data is saved as the maximum and minimum values measured in the scan interval within the sampling interval.
Using display data, how can I change the data save interval? To change the save interval for display data, change the display update interval. Can I receive email notification of alarm occurrences? Yes, with the email transmission function. When an alarm occurs, mail is sent to the specified email address. What are the sizes of display and event data?
What is the difference between event data and display data? Event data are the instantaneous values recorded at each scan interval. Display data are the maximum and minimum sampled values recorded within the display update time. I can't set a temperature range of 0. What is the allowable setting range for scaling? Omitting the decimal point, the values that can be set for scaling are to In this case, set it to "0.
The display of the scale setting upper limit value just automatically goes back 2 decimal places. The decimal place is determined by the scale lower limit value setting.
Set the decimal place in the scaling lower limit value. Can I view past display data? Using the Historical function, you can view a historical display of data in internal memory or external media.
What is the display update interval for recording display data at 1 minute intervals? Display and event data files. What is Event data? Event data are the instantaneous values recorded at each sampling interval.
They can be recorded at faster intervals than display data, and can therefore are used for analysis in greater detail. Is alarm information recorded to a file? What information is displayed in alarm summaries? The channel on which the alarm occurred, the time, and other information. Can I set alarms beyond the span setting range? Is there a way to delay occurrence of alarms?
